Description=GoToSocial Server

[Service]

# make sure this user and group exist and have read and write permissions in your GoToSocial folder.
# if they do not exist yet create them with "sudo useradd -r gotosocial"
# then give them permission with "chown -R gotosocial:gotosocial /gotosocial" (path to your gotosocial folder)
# you can adjust the users name according to your setup
User=gotosocial
Group=gotosocial

Type=exec
Restart=on-failure

# For speedier restart times, you can uncomment the following Environment line to have GoToSocial cache compiled
# Wazero artifacts in the given directory between restarts, so that it doesn't need to compile on startup every time.
#
# You may need to change the exact path depending on where you've got GoToSocial installed, for example if you've
# installed at "~/gotosocial" then change the value to "GTS_WAZERO_COMPILATION_CACHE=~/gotosocial/.cache".
#
# Whatever you do, make sure the dir exists and that the gotosocial user has permission to write + read from it.
#Environment="GTS_WAZERO_COMPILATION_CACHE=/gotosocial/.cache"

# change if your path to the GoToSocial binary is different
ExecStart=/gotosocial/gotosocial --config-path config.yaml server start
